Django 1.9 開發web項目

python version:     2.7.10

django version:     1.9

rest framework 3.3.2

建立項目:

django-admin startproject testweb

切換到項目中建立應用：

django-admin startapp app01

修改配置檔案settings.py,添加你的應用app01和rest_framework

    installed_apps = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'app01'

    'rest_framework',

    ]

app01檔案夾下建立templates檔案夾放入index.html模闆檔案

告訴你的應用模闆檔案路徑，修改settings.py

template_dirs=os.path.join(os.path.dirname(__file__),'templates')

最新版1.9已無需配置預設會到應用的templates檔案夾下尋找

    templates = [

    {

        'backend': 'django.template.backends.django.djangotemplates',

        'dirs': [],

        'app_dirs': true,

        'options': {

            'context_processors': [

                'django.template.context_processors.debug',

                'django.template.context_processors.request',

                'django.contrib.auth.context_processors.auth',

                'django.contrib.messages.context_processors.messages',

            ],

        },

    },

配置urls.py檔案

    urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^$', index),

啟動你的應用

python manage.py runserver 8080

背景管理

資料庫配置預設是sqlite,mysql的配置如下

    databases = {

    'default': {

        'engine': 'django.db.backends.mysql',

        'user':'root',

        'password':'',

        'name':'test',

        'host':'localhost',

        #'engine': 'django.db.backends.sqlite3',

        #'name': os.path.join(base_dir, 'db.sqlite3'),

    }

localhost:8080/admin/登入報no such table: auth_user錯誤

運作python manage.py syncdb即可自動建立所需表

注意：django 1.7.1及以上的版本python manage.py syncdb失效需要用以下指令

python manage.py makemigrations

python manage.py migrate

建立模型,修改models.py

    from __future__ import unicode_literals

    from django.db import models

    # create your models here.

    class mysite(models.model):

        title=models.charfield(max_length=100)

        url=models.urlfield()

        author=models.charfield(max_length=100)

        num=models.integerfield()

        def __unicode__(self):  

            return self.title 

        class meta:             #查詢時會以num排序

            ordering= ['num']

python manage.py shell 進入互動式資料查詢

from app01.models import *

m=mysite(title='django',num=2)

m.save()

m=mysite.objects.all()

m[0].title

m=mysite.objects.get(num=2)

m=mysite(title='django',num=3)

m=mysite(title='django',num=9)

m=mysite.objects.all().order_by('num')#升序

m=mysite.objects.all().order_by('-num')#降序

m.delete()

m=mysite.objects.all()[0:2]

管理界面管理你的模型admin.py

    from django.contrib import admin

    from app01.models import *

    # register your models here.

    admin.site.register(mysite)

使用表單出現csrf verification failed. request aborted.錯誤

urls.py配置

    from django.conf.urls import url

    from app01.views import *

        url(r'^$', index),

        url(r'^hello/$', hello),

靜态資源檔案配置
